Clear Haze Exchange

In this episode of Clear Haze Exchange, Marcus Hazelwood sits down with Greg Kwak, Vice President of Business & Product Development at Diversified Biotech, a Massachusetts-based company leading the charge toward sustainable lab consumables.
Greg shares how PlanetSafe, their plant-based alternative to traditional lab plastics, is reshaping research and healthcare through science-driven sustainability. The two discuss how innovation, transparency, and equity all play a role in making labs more sustainable — without sacrificing performance.

What you’ll learn:
  • How Diversified Biotech turned sugarcane into a plant-based replacement for single-use plastics
  • Why “scope 3 emissions” matter for research and healthcare facilities
  • How sustainable manufacturing reduces carbon impact by up to 90 percent
  • Why true sustainability also means equity for the people producing the materials
  • What circularity and “sustainably scalable” design mean for the future of science
